Thanks guys, all your posts have cleared it up for me.

For my first razor I went with a Gold Dollar 208, an inexpensive razor compared to all the Dovos and other recommended brands. I bought it to get into straight razor shaving at a lower cost at first to be sure it's for me. So I think I'll experiment with not oiling it frequently, maybe only once in awhile, and I'll check out how the blade does after a year of that. Then when I'm ready to step up to a higher quality / more expensive razor I'll know how often I'll need to do it.
